HAY-STACKER.

To all whom it may concern:

Be it known that I, DAVID C. Croon, a citizen of the United States,residing at Minooka, county of Grundy, and State of Illinois, haveinvented certain new and useful Improvements in Hay-Stackers, of whichthe following` is a specicat-ion.

My invention relates to hay-stackers and the object of my invention isto provide a hay-stacker which will remove the hay from the hay-rack anddeposit the same in a stack or within a barn.

Other objects will appear hereinafter.

Vith these objects in view, my invention consists generally in a.suitable frame, preferably mounted upon wheels, an endless conveyerextending longitudinally of the frame, a blower fan and an adjustablewind-stacker arranged at the end of the frame, and means forautomatically removing the hay from a hay-rack and depositing the sameupon said conveyer.

My invention further consists in a haystacker having the endlessconveyer, the

lblower and stacker as mentioned, in combination with a frame pivotallyconnected to the frame of the machine at one side of said Vconve er andextending transversel across drawings forming a part of thisspecication, and in which,

Figure 1 is aplan view of a hay-stacker embodying my invention in itspreferred form, Fig. 2 is an end elevation thereof, F ig. 3 is avertical, longitudinal section on the line mgm of Fig. 1, and Figs. 1and 5 are details of portions of the driving mechanism.

Referring now to the drawings, 1 indicates the horizontal rectangularframe of the device, which is preferably formed of timber, and adaptedto rest upon the bolsters of an ordinary farm truck of which 22 indicate the wheels, and 3 the body bolster. Ar-

Specification of Letters Patent.

ranged at one end of the frame 1 is a fan blower 4 which is preferablyarranged at an incline as shown in Fig. 3 with its open side 5 facinginwardly and upwardly. Arranged within the frame l is an endlessconveyer extending from the face 5 of the fan casing to the opposite endof the device. This comprises a pair of sprocket chains 6-6 connected bythe transverse bar 7 arranged at intervals thereon. The conveyer travelslongitudinally of the frame, the upper portion passing toward the fan.

8 indicates a bed plate arranged beneath the upper partof the conveyerand upon which, the hay to a great extent rests, the bar 7 drawing thehay along thereon. The chains 6 are arranged upon the sprocket wheels 99 fixed to the transverse shafts 10, one of which, is provided with abelt pulley 11 by which it is attached to the engine.

In Ausing the device, the hay rack to be unloaded is driven alongside ofthe stacker, and by suitable means to be described hereinafter, the hayis removed from the rack and deposited upon the conveyer. The conveyercarries the hay to the fan from whence it is carried through theWind-stacker to the hay-loft.

Hereinafter the term front of the machine will be used to designate theside upon which the hay-rack is arranged in unload- 1nd.

aIt will benoted by reference to Fig. 1 that the driving mechanism isarranged upon the back of the machine where it is less liable t0 becomechoked by the hay.

Secured to the rear member 1 of the frame and extending upwardlytherefrom are a pair of brackets 12-12, in which is mounted alongitudinal shaft 13 which is driven by the beveled gears 111 in turndriven from the shaft 10 by sprocket gearing 15. Pivotally mounted onthe shaft 13 and just within the respective bracket members 12 are thearms 16 connected at the outer ends by a brace 17 forming a rigid frame.The frame thus formed is of suthcient length to extend transverselyacross the bed of the tively, and the rake-bars 2l connecting the sameat intervals. When the device is in operation, the raking device orunloader rests upon the top of the hay upon the rack as illust-rated inFig. 2 and the rake-bars 2l being provided with a plurality of pins orteeth 22 draw the hay rapidly from the rack and deposit the same uponthe longitudinal conveyer.

28 and 24 indicate a cable and drum respectively, for raising andlowering the raking device or unloader.

As the hay on the longitudinal conveyer approaches the fan Casing 4a, itis drawn in through the opening 5 by the strong draft or suction createdby the fan, and blown through the wind stacker 25. The wind stacker isformed of the telescopic tubular members 2G and 27, the latter of whichis preferably provided with an angularly disposed discharge spout ornozzle 2S to enter the window of the hay-loft. Suitable means such as arack and pinion 29 and 30 is provided for raising the upper end section27, and a hand wheel 3l is provided for operating the same. The lowersection 26 is ointed as at 32 in order that the proper angularinclination may be had, and below the joint 32 it is provided with aswiveled joint 33, by means of which the direction of the spout 28 maybe adjusted.

34 and 35 indicate the cable and drum by means of which, the inclinationmay be adjusted, and 36 and 37 indicate a Worm and gear respectively foroperating the swivel joint.

Although I have shown and described specilic means for adjusting thewindstacker, it is to be understood that any suitable means inay beemployed whereby a proper adjustment may be had.

The fan 4 is driven by a belt 38- from a pulley 39 which is in turndriven by sprocket gearing 40 from t-he shaft of the main drive pulleyor band-wheel 1l.

It should be noted that the arms 16 are jointed as at 1G to facilitatefolding the device into small compass for transportation.

Having described my invention what I claim as new, and desire to secureby Letters Patent, is:

In a device of the class described a horizontal frame adapted to restupon a wagon truck, in combination with an endless conveyer arrangedwithin said frame, a pair of upwardly extending brackets arranged uponone side of said frame, an auxiliary frame pivotally mounted on saidbrackets and of suilicient length to extend across the frame andconveyor and also across a hay rack arranged alongside thereof, a pairof sprocket chains arranged on said auxiliary frame, a plurality ofrakes connecting said chains at intervals, said auxiliary frame beingpivoted upon said brackets a distance above said horizontal frameslightly greater than the depth of said rakes, and an adjustable windstacker arranged at one end of said conveyer, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
